As FitzRoy sails the Beagle to Bahia, he starts to buckle under the pressure of being captain when some of his crew succumb to tropical disease and the memory of a departed colleague haunts him. Back on land, Darwin and Syms are given a guided tour of Rio and its surrounds by yet another priest with questionable morals, while Derbishire runs from the long arm of the admiralty’s accounts department.
